It combines an Arduino-compatible processor with a light sensor, a temperature sensor, a 3-axis accelerometer, a joystick, a set of pushbuttons, a slider, an RGB LED, and a buzzer.

Nice method and analysis. The temp sensor 3 pin devices are simple and cheap but good for 0.5 deg C precision or nearly a full degree in human measure.

The project is equipped with a DHT11 sensor to read the room's temperature and an LCD to display this temperature reading and the speed the motor is currently running at.

I’ve tried the DHT11 sensor modules at both Vcc 3.3V and 5.0V, and at both voltages the humidity values are bad. dfrobot has introduced a V2 DHT11 sensor module that changes the 10K pull-up to 4.7K.

The PCB Direct virtual breadboard has been created to allow anyone to create interactive virtual breadboard circuits for platforms such as Arduino, ARM, PIC, Raspberry Pi and more, with the ...
